The hex color #0D1CBD, also known as International Klein Blue, presents specific accessibility considerations for web developers. Its high saturation and deep hue mean that careful attention must be paid to contrast ratios, particularly when used for text or interactive elements. According to WCAG guidelines, sufficient contrast is necessary to ensure readability and usability for individuals with visual impairments. A light color should be used as foreground. Ensuring proper contrast is crucial for users with low vision or color blindness. Furthermore, providing alternative cues like text labels or icons can enhance accessibility for users who might have difficulty distinguishing colors alone. This color should be tested with accessibility tools to confirm that it meets the contrast requirements for different user needs.
